District of Muskoka. 2024. "Lake System Health Water Quality Monitoring Program Data" (dataset). 1.0. DataStream.

Funding Sources

The program is included in the operating budget of The District Municipality of Muskoka with additional support from the Ontario Ministry of Environment, Conservation and Parks.

Data Collection Information

A composite sampler is used to collect an integrated sample of the water column from the surface to the Secchi depth. Water samples are analyzed in a lab. Duplicate samples are collected for Total Phosphorus analysis.

Data Processing

Duplicate samples for Total Phosphorus are compared. If samples have a greater than 25% variance, the higher reading is typically discarded due to contamination. Duplicates should be averaged to obtain the TP concentration for the site.
